Abstract

A method of monitoring an electrochemical second order half-cell (1, 101) is provided, as is a measuring probe with at least one electrochemical second order half-cell (101), a control- and/or regulation unit (7) to close an electrochemical contact between the half-cell and a measuring medium (8), and with at least one temperature sensor (9, 10). The half-cell includes an electrolyte (4) and a first conductor element (2) in contact with the electrolyte and which holds a first electrical potential (E.sub.1). The half-cell also has a second conductor element (3) in contact with the electrolyte, the second conductor holding a second electrical potential (E.sub.2). The two conductor elements (2, 3) comprise the same metal. The first conductor element has a coating (6) of a low-solubility salt of the same metal. The control- and/or regulation unit includes a program for executing a method of monitoring the electrochemical half-cell.
